' To; all whomz't may concern-:1

Be it knownv that I, EDWARD: W; :WooLLnY, a citizen of the United States, and'aresident of Jersey City, in theicountyiof Hudson and State of New Jersey have invented certain new and usefullnaprovements in Clutch and Mechanism, of which the fol lowing is a specification. v I

This invent onjel'ates to a clutch and regulating mechanism.

It is specially applioableto rehicl'es elee' trio trolley cars the-like, but the elementsof the inventiona're useful for variousother purposes. 'I'ES OIgiLHIZELtIO-H comprises essentially areservoir that is charged 7 with compressedairby aco-i-n pressor which [latter is driven-by an electrically controlled clutch. The clutch-iscontrol l'ed by anelectric switch, which iscontrol-led by a regu-' lating and signal cylinder, and the l'atter'is controlled by V the pressure of the air. in; the

reservoir. -The operatingelernents are thus "interdependent of one anotherfland provide means fort-he proper predetermined pressures in the reservoir,operating when said pressure falls too-low and s-topplng when the required pressure has been. obtained.

The regulating and cylinder blows'a whistle when either limit of pressure is reached, apprising the operator of the limiting pressures of the invention.

latter the current flows through and. then into the coils of the spools, The

A wirer220 extends from the feed wire 59 andleads to the switch 221, that is similarto the switch having the handle 138, and awire 222 connects said switch22l with the wire 57. To use the invention and should there be no charge of compressed air in the reservoir 95, and supposing the regulating cylinder 166 inoperative, the motorman being at end of car adjacent to switch boX 58 opens the switch having the handle 137, the switch 221 being open and closes the'operating switch Electric current then flows from the starting box through the feed wire 59 to --said switch with the handle 138, andthrough the branch wire 211 V into the feed wire 57, which, conducts the current to the contact ring 45. From the wire 60 conducts the current to the contact ring 46, and from thielatter the current is conducted by means of the wire56 back to the starting box 55.1 The magnets areexcited bythe said current and the. male mem her 36 of .the clutch isattra'cted toward the female. member '31 thereof, closing said members; With the closing of'the members of the clutch, the rotation of theaxle'21 is transmitted to the gear 66 by the pinion 65. The piston 87 in the compressor 86 is caused to reciprocate when the spur gear 66 ro- 'tates, and air isdrawn into said compressor 1 histle 184 and located atthe other end of binding post. A

the wire 62 86 through the inlet valve 90 and forced throughthe flexible tubing 88 and piping 96 into the reservoir until the requisite pressure is obtained. After the pressure has reached its maximum point the operator opens the switch having-the handle 138 whichopens the circuit ofthe feed wires 57 and 59 and no current enters thespools 35 of the magnets in the female member 31 of the clutch. The springs 41, 43 therein disengage the members of the clutch which stops the reciprocations of the piston 87 of the compressor 86. The springs 41 and 43 bear between the members of the clutch and tend to separate them.

In case the automatic appurtenances of the invention are in proper operative adjustment the switch 221 and the switch with the handle 138 are kept open, and the switch with the handle 137 the wire 59 then flows through the wire'218, through the switch having the handle 137,

and from the latter switch current flows through the wire 217 to the binding post 159. Under the supposition that there is no pressure in the reservoir 95 the piston 169 in the regulating cylinder 166 is at the lower end of its stroke, by virtue of which the contact lever 196 moves the contact screw 198 to bear against the flexible bar 202..

Current will then flow through the wires 214, and 215 to excite the magnet 141. The said magnet 141 attracts the armature 147 which causes the knife blade 156 to register with the contact springsl62 and current flowsthrough the branch wire 212, and from thence through the wire 57 and the spools torman that the pressure in the reservoir is below the normal predetermined amount. The escape of air through the ports 170, 171 and 181 assists thedescent of the piston 169 and lever 196; The members of the clutch being engaged, the compressor 86 forces compressed air into the reservoir. The spring 173 controls the amount of pressure required to force the piston 169 upwardly, and, if above the predetermined normal amount, it rises until a circumferential port 170 registers with the branch port 181, and air is again forced into the piping 183 and the Whistle 184 blown. As soon. as the piston has reached its top or upper position, the vcontact screw 198 disengages from the the electric circuit of the tension of the the end of the lever bar .202, which breaks the magnet 141, and spring 149 pulls down 145having the fork 148;v This causes the is closed. Current from 7 blade breaks the circuit of the'feedwires' the male member fblade 156 to disen'gage from the mana e springs 162." The latter position of'the said 57 I and 59'. The spools of the magnets not now beingexcited the springs 41, 43 force 36 from the fema'lefm'ember of the clutch, and-the reciprocations of the piston 87 in the compressor- 86 are stopped.
